Explore how the cross transformed from a shameful Roman execution device into Christianity’s central symbol. Discover early Christian attitudes, artistic developments, and Constantine’s pivotal role in redefining its meaning. Gospel accounts of Jesus’s execution do not specify how exactly Jesus was secured to the cross.
Context Explanation
Yet in Christian tradition, Jesus had his palms and feet pierced with nails. Even though Roman execution methods did include crucifixion with nails, some scholars believe this method only developed after Jesus’s lifetime. I understand cross_validate and how it works, but now I am confused about what cross_val_score actually does. Can anyone give me some example?

Insight Material
Intuitively cross entropy says the following, if I have a bunch of events and a bunch of probabilities, how likely is that those events happen taking into account those probabilities? If it is likely, then cross-entropy will be small, otherwise, it will be big. In Mathematics Kullback-Leiber divergence (KL), Cross-Entropy (CE), Entropy (H) always mean only one thing, but the term Entropy unfortunately can vary from the scientific community. In any case, the good book on the subject "Information Theory is the book "Elements of Information Theory" by Thomas M. Cover, Joy A.

Thomas." from 1991. 59 I used to apply K-fold cross-validation for robust evaluation of my machine learning models. But I'm aware of the existence of the bootstrapping method for this purpose as well. However, I cannot see the main difference between them in terms of performance estimation. This expectation is the "cross-entropy". Now here comes my question: The book I am reading (Deep Learning by Goodfellow et al) mentions several attractive properties of using the negative log-likelihood (like consistency).
Meaning, in 5-fold cross validation we split the data into 5 and in each iteration the non-validation subset is used as the train subset and the validation is used as test set.
